Alto Metals (ASX:AME) reports it has received further ‘outstanding’ gold results at the Indomitable Camp, located within the Sandstone Gold Project in Western Australia.
The company says reverse circulation (RC) drilling at Indomitable was designed to both follow-up on a ‘high-grade’ structure identified from previous drilling outside the resource to the northwest and test strike extensions of the existing mineralisation.
New assay results reported are from 1m photon assays relating to 40 RC holes drilling at Indomitable comprising a mix of 40m by 40m spacing, 80m step-out and three 20m by 20m holes for a total of 5,442m at an average downhole depth of 136m.
Significant results received from drilling northwest of Indomitable include 25m @ 7.5g/t Au from 41m including 6m @ 22.3g/t Au from 56m and 14m @ 1.5g/t au from 93m including 3m @ 2.2g/t Au from 94m in SRC853, 15m @ 2.8g/t Au from 44m including 3m @ 12.4g/t Au from 45m from SRC826, and 9m @ 1g/t Au from 34m in SRC852.
Hole SRC848 drilled on the eastern side of Indomitable include intersected 15m @ 2.1g/t Au from 62m including 10m @ 3g/t Au from 67m.
Results from extensional drilling on the western side of Indomitable include 8m @ 2.4g/t Au from 10m in SRC819, 11m @ 0.6g/t Au from 9m including 5m @ 1.1g/t Au from 15m in SRC824, 9m @ 1.3g/t Au from 54m including 5m @ 2.1g/t Au from 54m and 7m @ 1.6g/t Au from 120m including 1m @ 5.9g/t Au from 122m in SRC849.
Extensional drilling completed on the southern extent of Indomitable intersected 31m @ 0.6g/t Au from 61m including 5m @ 1.1g/t au from 64m in SRC839, 10m @ 1g/t Au from 60m including 1m @ 3.6g/t Au from 60m in SRC843, and 29m @ 1g/t Au from 69m including 7m @ 2.2g/t Au from 69m and 10m @ 1.4g/t Au from 119m including 6m @ 2.1g/t Au from 119m in SRC847.
Hole SRC837 drilled to the northwest of Indomitable also intersected 4m @ 2.1g/t Au from 113m including 1m @ 7.3g/t Au from 114m.
Alto Metals Managing Director Matthew Bowles said these latest results are outstanding, highlighting the intercept in SRC853 which presents the opportunity to extend the shallow mineralisation at Indomitable which remains open in all directions.
“We are very pleased with the results from this year’s drilling, which continues to demonstrate the potential for Indomitable to be a much larger system, and places the company in a great position to deliver an updated resource estimate in the March quarter 2023.
“We are also excited to have commenced our maiden regional drilling program at the historic Oroya Mine”
We are also excited to have commenced our maiden regional drilling program at the historic Oroya Mine, where previous mining was focused only on bonanza style mineralisation within the reef and much of the surrounding mineralisation was left unmined.”
Alto reports the intersection in hole SRC853 highlights the continuity of the ‘high-grade’ structure intersected in previous drilling, and these north to south trending stratigraphic units have a width of 50m to 100m and are developed as sub-vertical ‘high-grade’ mineralised structures.
This structure also hosts the previous ‘high-grade’ intersections including 10m @ 3.2g/t Au from 69m in SRC687, and 15m @ 3.8g/t Au from 44m including 2m @ 18g/t Au from 49m in SRC626 located 20m to the north and south of SRC853 respectively.
Extensional drilling west of Indomitable has intersected shallow gold including SRC819, 824 and 849 which have extended mineralisation further to the west and remains open.
At the southern extent of Indomitable, extensional drilling on 80m spacing has intersected broad zones of oxide gold mineralisation, extending the mineralised footprint south.
The company says the Indomitable Camp is currently defined over a more than 2.5km strike length and sits within an over 20km northwest to southeast trending gold corridor which also hosts the Vanguard and Havilah deposits within the Alpha Domain priority target area.
Alto reports its drilling program for 2022 will continue to focus on both resource growth and testing priority regional targets including around 4,800m of RC drilling to be completed at Indomitable East, and a first pass RC drilling program for around 2,000m is currently underway at the Oroya Mine testing potential ‘high-grade’ extensions of the Sandstone Reef.
A soil sampling program has been completed over Sandstone North as part of the regional exploration program, and is with Portable PPB for analysis with detectORE technology.
The company anticipates an updated mineral resource will be completed by the March quarter of 2023 which will include the follow-up drill results from Lord Nelson and Juno, and the results from the ongoing infill and extensional drilling program at Indomitable including a maiden resource for Indomitable East and Musketeer.
Alto Metals is a gold exploration company focused on the Sandstone Gold Project in the Archaean Sandstone Goldfield around 600km north of Perth in the East Murchison Mineral Field of Western Australia.
